RAIL-TIE.

Specification of Letters Patent.

Patented Aug. 13, 1912.

Application filed March 3, 1911. Serial No. 612,090.

To all whom z'tmay concern: Be it known that I, JOHN W. Draw, a citizen and subject of Great Britain, residing at Lunenburg, in the county of Lunenburg and Province of Nova Scotia, Canada, haveinvented new and useful Improvements in Rail-Ties, of which the following is a specification.

My invention relates to railroad ties and moreparticularly to a metallic tie adapted to be made with a solid base and having recesses therein so constructed as to receive the base flange of the rail within said recesses, said rail bein locked in place by a removable block WhlCh is preferably counter-sunk into the base of the tie, whereby all lateral -movement of the rail and spreading thereof are prevented. v

More specifically stated my invent-ion comrises improvements on the. tie shown in atent Number 292,421 granted to, J. J. Du Bois oil-January 22, 1884. Because of the peculiar shape of the locking blocks D in said patent,.and the under-cut formation of the recesses inwhich said blocks are set, it

1s 1mpossible to insert said blocks after the rails are in place except by sliding them in;

from one'side of the tie. The inefiiciency of this method of locating them willbe more readily understood when'it is pointed out that it prevents the locking bolts E-from being inserted before the tie is laid, and necessitates the raisin" ofjthe tie or thoundermining of the roa bed before saidbolts may be Iplaced in position. t is the primary object of my invention to overcome these objections to'the Du Bois tie and to provide a constructiomnvhich may be easily operated and thus saver-considerable time in the laying of the tie which would be lost were the Du bois tie used. ,I accomlish this result by making the,- locking locks of a different form and. shape, so as to permit the locking bolts to-be placed in position before the tie is laid; 'Other difierencesnf construction will be brought out more 'clearly hereinafter.

Further objectsof my invention are to provide a tie which may be manufactured at a low cost'and which shall absolutely prevent the rails from spreading except through the natural expansion and contraction of the tie caused by'heat and cold, and to construct a tie which because of its simplicity and rigidity will be more effective and durable than those which have heretofore been embeing accompanied by the construction.

shown by which the locking blocks are arranged so as both to fall on the sameside of adjoining rails, and also by the fact that the keepers formed integral with the base both point in the same direction-and extend out over a raised portion whereby the necessity of raising and lowering the rail is obviated;

With the foregoing andother objects in view my invention consists in such details of construction and in the arrangement and combination of parts as-will be hereinafter morexfully described and specifically pointed out'in the appended claim.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like' or corresponding parts throughout the several views, and in .which Figure 1 is a view in perspective of my improved tie a section thereof being broken 'from the central portion in order to permit said tie to be illustrated in detail. Fig. 2 is a longitudinal, sectional view of one end of the tie showing the locking block about to be placed in position, the rail being omitted. Fig. 3 is'a View similar-to'Fig. 2 with the rail and locking block in position. Fig. 4 isa perspective view of one end of my improved tie showing the formationof the recesses therein, and Fig. 5 is a perspective view of a locking block; I

In reducing my invention to practice I construct a tie having a solid base 1. It will be understood that any desired material adapted for the purpose may be employed as my invention does not comprehend any particular substance. It will also I be understood that this base maygbe made of any thickness preferred or length desired,

in order to conform with the requirements of particular circumstances and in order to make the tie of any desired weight. The 9 thickness of the base is increased at the points 2 and 3 which port-ions are so con-. structed as to permitrecesses 4 to be cut therein without, decreasing the strength of the tie. The "recesses 4 are undercut as shown in order to receive the base flange of a rail 5. Said rail rests upon a raised table edge of the table or bed 6 for any desired distance. Contrary to the shape of the recesses in Patent Number 292,421 above mentioned I form these recesses with vertical sides in order that locking blocks 8 may be positioned therein without the necessity ofsliding said blocks into place from one side of the tie, as will be readily seen upon reference to Figs. 2and 3. Said locking blocks have one edge extended at an upper portion thereof so as to form the projecting lip 9, which fits over the base flange of the rail it thus acting in conjunction with the under-cut recesses befo're mentioned in locking said rail in place.

Bolts. 10 extend upwardly through the base of'the tie and pierce the locking blocks as shown so as to permit nuts 11 to be applied thereto, thus locking said blocks securely in position. It will be-understood that any other "fastening means than bolts may be used as desired, and that the bolts may be of any desired type as can also the nuts in order to prevent said nuts from working loose or from being removed.

It w1ll be seen from the foregoing that inasmuch as the sides of the recesses 7 and the blocks 8 are vertical the latter may be inserted in said recesses by passing them downwardly over the bolts 10 thus obviating the necessity of a sliding movement such -as that necessarily employed in the patent- Inasmuch as the blocks above referred to. 8 are disposed in recesses-below the level of the base flanges of the rail all lateral movement of said blocks is prevented, thus looking the rails and preventing them from spreading apart, This countersunk con- I struction also prevents the possibility of the blocks turning upon the bolts, for it provides solid walls at two ends of the blocks and prevents the latter from moving upon the base flange of the rail which movement would of course cause more -'or less Wear.

From the foregoing it will be seen that I have provided a rail tie which is simple ahd which may be cheaply manufactured, but

which at the same time is highly efiicient and will rigidly hold the rails in place. Because flopiel of this patent may be obtained for five cents each, by ad Washington, D. G.

fastened inplace without unnecessary delay or trouble.

I desire it to be understood that slight changes in the construction and in the ar- .rangement and "combination of the several parts may-be resorted to without departin from the spirit of myinvention, provide such changes fall within the scope of the appended claims. 5

Having thus fully described my invention,. I

what I claim as new anddesire to-s'ecure by Letters Patent, is

In a device of the characterdescribed, a

solid base, said base provided withthickened portions, one of said thickened portions be- .ing near one end, the other being spaced a considerable distance from 'the other end, ;said thickened portions provided with un-- dercut recesses, beds adapted to receive the to be positioned within said second named recesses, said locking blocks having perpendicular sides, one end of said locking blocks adapted to lie flush with theupper surface of said base portion, extensions formed upon the other ends of said locking blocks adapte to extend over' the base flange of rails, said base flanges engaging one of their vertical sides, bolts adapted to extend through said base portion and through said locking blocks,

said base portion provided with cut-out porthe upper ends of said bolts, semi-circular JOHN. w. DEAN..

base flanges of rails adjacent to said underlcut recesses, said beds being in the same horizontal plane as the upper surface of said base, other recesses of greater depth adja- ;cent to said beds, said lastnamed recesses I having vertical sides, locking blocks adapted .cut-out portions formed upon said locking blocks for the reception of one side of said nuts, whereby said nuts lie fiat upon the ;same thereby locking the said rails in place for the purpose described.
